APPLIANCE FOR SECURING FLANGED RAILS TO METAL SLEEPERS.

SPECIFICATION formingpart ofLetters Patent No. 513,838, dated January30, 1894.

Application filed August 24, 1893. Serial No. 488,997. (No model.)Patented in England September 2, 1892, No. 15,788-

To all whom it may concern: 7

Be it known that I, EDWARD HERBERT STONE, a citizen of England, residingat Simla, India, have invented a new and useful Appliance for Adjustably Securing Flanged Rails to Metal Sleepers or Bearing-Plates, (forwhich I obtained a patent in Great Britain, September 2, 1892, No.15,788,)of which the following is a specification.

This invention relates to means for securing flanged rails to metalsleepers or bearing plates in such a manner that the rail can be readilyfixed or removed and that several variations of gage can be made to suitcurved parts of the line without'having tochange the sleeper or theposition of the bearing plate.

Figure 1 of the accompanying drawings is a transverse section and Fig. 2is a plan showing the fixing of a rail to a bearing plate according tothis invention.

The special featureof the invention is the use of a key A and a distancepiece B in combination with the bearing plate or sleeper so that thejaws O. D can beplaced sufficiently wide apart to allow of a rail beingreadily put in place or removed. The distance piece B determines thedefinite gage and the key A tightens up and keeps the rail firmlysecured. For normal gage the distance piece B is applied outside eachrail. For the widest gage it is applied on the inside of each. Anintermediate gage between the normal and the widest can be obtained byapplying a distance piece inside the one rail and outside the other. Agraduation of gage from normal to intermediate or from intermediate towidest is obtained by the substitution of a second key for one of thedistance pieces, the

adjustment of the two keys (one on each side of the rail) allowing thegraduation to be offected over such length as may be desired, instead ofmaking a sudden change in gage between one sleeper and the next.

The distance piece B is by preference formed as a gib with two ears orlugs to give it greater security against being tipped backward, and witha taper corresponding with the taper of the key. The jaws G D beingsimilarly inclined the rail is then fixed at right angles to the bearingplate.

The jaws or clips 0 D are shown as being plate.

punched up from the body of the bearing They might obviously be fixed onthe plate by riveting or otherwise, or the plate itself might be castwith these. Also the mode shown of fixing the rail to a bearing plate isobviously applicable in the case of a metallic sleeper, having clips orjaws punched up or otherwise formed on or fixed to the sleeper.

The bearing plate shown in the drawings is dished in order to increaseits stiffness and also to give the bed for the rail an inclinationsuited for its tilt. The jaws G D are punched uppreferably with acorrugation in the middle, forming as it were an abutment to supportthem against the strain to which they are subjected by keying the railin position. When a metal sleeper is employed instead of a wood sleeperwith bearing plate, the upper face of the rail seat may be inclined likethat of the bearing plate to give the tilt for the rail, and the jawsmay be similarly corrugated.

It is to be understood that I make no general claim to the use of metalbearing plates or sleepers having jaws either plain or corrugated tohold rails secured in them by keys, but,

Having thus particularly described the nature of this invention and thebest means I know for carrying the same into practical effect, I claim--The herein described fastening for flanged rails, consisting of a metalbed-plate, provided with jaws between which the rail is lo cated, atapering distance piece having lugs or projections on its tapering side,said distance piece being located between one of the jaws, and one sideof said rail, and a wedgeshaped key inserted between the opposite jawand other side of the rail, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 22d day of February, A. D.1893.
